That’s a bang – two neutron stars collided on August 17th, creating such an explosion it allowed astronomers to see both light wave and gravitational waves at the same time, this rare event also created some heavier minerals like gold and platinum, the explosion it self even got it own name of KILONOVA. Now this event happened 130 million light years away, which is lucky for us. As these type of events are known to destroy the regions around them.
Astronomers have only been able to see gravitational waves for less than a second. but this event created gravitational waves that where detectable for over a minute
